Airi has traits very similar to her brother. She has below-neck light grey hair and grey eyes, the same as her brother. She wears the Royal Officer Academy school uniform.
She worries a lot about her brother.
- The flute she uses seems to be stronger than the one used by Hayes, seen when she overwrites her commands in the anime.
- She also seems to see Lux as more than just a brother. This could explain why she gets jealous of his harem.
